[0002] The existing lithium battery top cover assembly equipment needs to cooperate with manual labor to complete the product assembly. Manually place the lithium battery top cover with the front side facing up on the jig, then manually cover it with a cover plate. Then, manually flip the jig with the lithium battery top cover to the back and put it on the conveyor belt. The automatic equipment grabs the jig and places it on the workbench. The product is sent to each process for processing through the rotating workbench. After the product processing is completed, the robot takes out the jig and puts it on the discharge conveyor belt. Manually disassemble the jig components and take out the product.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

The flip clamping mechanism 5 includes a rotating sleeve 501, which is connected to the slider 104 through a bearing. A power rod 502 is movably connected inside the rotating sleeve 501. The rotating sleeve 501 can rotate and slide relative to the power rod 502. A guide groove is provided on the power rod 502. A protrusion 505 is fixedly connected to the inner wall of the rotating sleeve 501. The protrusion 505 cooperates with the guide groove. A splint 506 is fixedly connected to the end where the two rotating sleeves 501 are close to each other. The splint 506 is used to clamp the fixture 4. A rubber layer is provided on the inner side of the splint 506 to increase the friction between the splint 506 and the fixture 4 and ensure the stability of clamping. A pushing mechanism 7 for pushing the flip clamping mechanism 5 and the elastic telescopic rod 6 is installed on the fixed seat 102.

[0027] The flip clamping mechanism 5 also includes a first spring 507 and a rotating plate 508. The rotating plate 508 is rotatably connected to the inside of the rotating sleeve 501. The first spring 507 is arranged between the rotating plate 508 and the power rod 502. The end of the power rod 502 away from the first spring 507 is fixedly connected to a limiting rod 509. The limiting rod 509 is slidably matched with the elastic telescopic rod 6. The limiting rod 509 is used to ensure that the power rod 502 can only translate but not rotate.

[0028] The guide groove includes two spiral grooves 503 and two straight grooves 504. The straight grooves 504 are connected to the spiral grooves 503. When the spiral grooves 503 cooperate with the protrusions 505, the movement of the power rod 502 will cause the rotating sleeve 501 to rotate. When the straight grooves 504 cooperate with the protrusions 505, the rotating sleeve 501 does not rotate during the movement of the power rod 502, and when the protrusions 505 move from one end of the spiral groove 503 to the other end, the rotating sleeve 501 rotates 180°.

[0029] The elastic telescopic rod 6 includes a fixed sleeve 601, which is welded in the slider 104, and a movable rod 602 is slidably connected in the fixed sleeve 601. The end of the movable rod 602 away from the splint 506 extends out of the fixed sleeve 601, and a second spring 603 is fixed between the movable rod 602 and the fixed sleeve 601. A limiting groove 604 is provided on the top of the movable rod 602, and the bottom end of the limiting rod 509 is slidably connected in the limiting groove 604. When the movable rod 602 is pushed, the thrust of the second spring 603 will move the fixed sleeve 601, and the fixed sleeve 601 drives the slider 104 to move. When the slider 104 moves to the other end of the slide groove 103, it will no longer move. At this time, continuing to push the movable rod 602 will cause the second spring 603 to be compressed.

[0030] The pushing mechanism 7 includes two fixed plates 701, and the two fixed plates 701 are connected to the two fixed seats 102 by screws respectively. A bidirectional screw rod 702 and a sliding rod 703 are arranged between the two fixed plates 701. The bidirectional screw rod 702 is connected to the fixed plate 701 by bearings, and the sliding rod 703 is fixedly connected to the fixed plate 701. A second motor 704 is connected to one side of the fixed plate 701 by bolts, and the output shaft of the second motor 704 is connected to the bidirectional screw rod 702 by a coupling. Two symmetrically distributed translation blocks 705 are arranged on the bidirectional screw rod 702 and the sliding rod 703. The translation block 705 is threadedly connected to the bidirectional screw rod 702, and the translation block 705 is slidably connected to the sliding rod 703. When the second motor 7 04 When the bidirectional screw rod 702 is driven to rotate, due to the guiding and limiting effect of the sliding rod 703, the two translation blocks 705 will approach or move away from each other. A push plate 706 is fixedly connected to the rear side of the translation block 705. The push plate 706 is fixedly connected to the movable rod 602. The push plate 706 is located on both sides of the flip clamping mechanism 5. The push plate 706 is driven to move by the translation block 705, and the push plate 706 drives the movable rod 602 to move. When the movable rod 602 retracts a certain distance into the fixed sleeve 601, the push plate 706 contacts the power rod 502, and then the push plate 706 starts to push the movable rod 602 and the power rod 502 to move at the same time, and the rotating sleeve 501 is rotated by the movement of the power rod 502.

[0031] The mounting frame 2 includes a second pillar 201, which is welded to the top of the base 1. The top of the second pillar 201 is connected to a mounting plate 202 by screws. The turntable 3 is rotatably mounted on the top of the mounting plate 202. The bottom of the mounting plate 202 is connected to a first motor 203 by screws. The output shaft of the first motor 203 is fixedly connected to the turntable 3.

[0032] Working principle: When in use, the turntable 3 is driven to rotate by the first motor 203, and the jig 4 with the product installed is moved between the two fixed seats 102, and then the jig 4 is lifted up by the lifting cylinder 105, so that the jig 4 is located between the two clamping plates 506, and then the bidirectional screw rod 702 is driven to rotate by the second motor 704, and the bidirectional screw rod 702 drives the two translation blocks 705 to approach each other, so that the two push plates 706 approach each other, and the push plate 706 drives the movable rod 602 to move, and through the elastic force of the second spring 603, the second spring 603 drives the fixed sleeve 601 to the jig 4 , the fixed sleeve 601 drives the slider 104 to move toward the fixture 4, so that the entire flip clamping mechanism 5 moves toward the fixture 4, so that the two clamping plates 506 clamp the fixture 4, and the lifting cylinder 105 retracts to prevent the lifting cylinder 105 from blocking the flipping of the fixture 4. At this time, the slider 104 moves to the other end of the slide groove 103, and the push plate 706 continues to drive the movable rod 602 to move. Since the slider 104 can no longer move at this time, that is, the fixed sleeve 601 can no longer move, the movable rod 602 retracts into the fixed sleeve 601, and the second spring 603 is compressed.

[0033] As the movable rod 602 retracts, the push plate 706 contacts the power rod 502. At this time, the protrusion 505 is located at one end of the spiral groove 503. The push plate 706 begins to drive the movable rod 602 and the power rod 502 to move toward the direction of the fixture 4 at the same time. The power rod 502 retracts into the rotating sleeve 501. Through the cooperation of the spiral groove 503 and the protrusion 505, the rotating sleeve 501 starts to rotate, and the rotating sleeve 501 drives the clamping plate 506 to rotate. When the protrusion 505 moves from one end of the spiral groove 503 to the other end of the spiral groove 503, the clamping plate 506 drives the fixture 4 to flip 180°, and the protrusion 505 enters from the spiral groove 503 into the straight groove 504. At this time, the lifting cylinder 105 extends again, and the lifting cylinder 105 is against the bottom of the fixture 4.

[0034] Then the second motor 704 reverses, so that the two translation blocks 705 drive the two push plates 706 to move away from each other, and the first spring 507 rebounds to make the power rod 502 extend out of the rotating sleeve 501. Since the protrusion 505 cooperates with the straight groove 504 at this time, the power rod 502 will not drive the rotating sleeve 501 to rotate. When the push plate 706 is out of contact with the power rod 502, the power rod 502 extends from the rotating sleeve 501 to the maximum length. At this time, the protrusion 505 enters the spiral groove 503 from the straight groove 504 again and returns to Initial state, then the push plate 706 continues to drive the movable rod 602 to move, when the movable rod 602 extends from the fixed sleeve 601 to the maximum length, the movable rod 602 drives the fixed sleeve 601 away from the fixture 4, the fixed sleeve 601 drives the slider 104 away from the fixture 4, so that the clamping plate 506 is away from the fixture 4, so that the clamping plate 506 releases the fixture 4 and returns to the initial state, and then the lifting cylinder 105 drives the fixture 4 to move downward, and the fixture 4 is placed on the turntable 3, and the above process is repeated to continuously flip the product.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
